Application led .Tune 30, 1924. Serial No. 723,406.

This invention relates to eervescent salt un'its.

An important object of theinvention is to provide a simple and eiilcient means Whereby the packaging of certain medicinal salts may be accomplished in such a way that the package may be utilized `as a receptacle or container through the instrumentality of which the salt may be easily introduced into a bath and submerged to facilitate medicinal conditioning of the bath.

A further object of the invention is to provide in connection with the device an effective means adapted to exclude moisture from the package content during storage and shipment, and yet capable of being readily removed immediately prior to the introduction of the package into the bath in order to permit the ingress of water to facilitate activating effervescence of the package content.

Another object of the invention is to provide a container so constructed as to direct the gas accumulated within the same upon the entrance of water, to a given restricted outlet opening in such a way as to facilitate further ingress of water.

Other objects and certain advantages of the invention will become apparent from the following description taken in connection with the accompanying drawings in which- Figure l is a view in elevation of the article wrapped in a moisture-excluding wrapper.

Figure 2 is a central vertical sectional View through the container,

Figure 3 is a. bottom view of the container or package.

Figure 4 is a fragmentary sectional View showing on an enlarged scale the upper portion of the container with the tip removed to provide an outlet opening for the accumulated gases.

Figure 5 is a central sectional view through the receptacle cap yor closure prior to its application.

In the drawings wherein for the purpose of illustration is shown what I at present consider the preferred form of my invention, the numeral 5 indicates a cone shaped container preferably constructedvfrom paper', cardboard, or other similar mate-rial. This container is normally closed at its up. per end and is provided at its lower or enlarged end with a closure indicated as a whole by the numeral 6. rlhis closure is preferably constructed from metal so stamped or shaped as to provide, relatively near its peripheral edge, a depending flange flange 8 forming with the depending ange 7 a groove 9 adapted for the reception of the lower or enlarged end of the container 5. 'lhe closure 6 when applied to the con- T bent upwardly to provide a peripheral tainer 5 is locked in position thereupon by 65 forcing the depending and peripheral flanges 7 and 8, respectively, into impinging engagement with the container 5, as shown in Figure 2.

The container 5 is adapted for the recep- 70 tion of a quantity of crystalline material 10 composed of bicarbonate of soda and acid sodium sulphate with which is mixed a quantity of radium-barium chloride in the manner hereinafter more particularly described A satisfactory quantity of bicar-l bonate of soda and acid sodium sulphate has been found to be ten grams, there being two parts by weight of bicarbonate of soda to one part by weioght of acid sodium sulphate.

The amount of radium-barium chloride employed is relatively small: nine micrograms of barium chloride and one microgram of radium have been found satisfactory When used With`each container carrying bicarbo-nate of soda and acid sodium sulphate to the `amount and in the proportions named.

l'Vhen packaging the material the bicarbonate of soda and the acid sodium sulphate both in crystalline form are mixed together and introduced into the container. The radium-barium chloride dissolved in a suitable amount of alcoholV may be incorporated with the bicarbonate of soda and acid sodium sulphate -by adding it at this time.

The alcoholic solution of radiumbarium chloride u on being added to the bicarbonate of so a and acid sodium sulphate is distributed throughout the material lafter tions 11 adapted to permit ingress of water to effect reaction of the-bicarbonate of soda and acid sodium sulphate causing effervescence by reason of which the radium emanation is distributed throughout the bath as hereinafter more particularly described.

In order to effectively seal the container against moisture during storage and shipping I have provided the same With a Wrapper 12 perferably of such a moisture eX- cluding material as tinfoil. This Wrapper,

although serving to effectively seal the container to the exclusion of moisture during storage and shipment, is nevertheless adapted to be readily removed when it is desired to place the article in use.

Before placing the article in luse the Wrapper 12 is removed from the container after which the upper end or point 13 thereof is torn or otherwise removed'to provide a vent or opening 1li.y The article is then introduced into the bath and submerged whereupon the water entering the container 5 through the several openings 11 dissolves the bicarbonate of soda and acid sodium sulphate so that they react producing carbon dioxide which passes up through the material contained Within the container and escapes through the opening 14 provided therein by removing the upper or pointed end as described. The gas escaping through the opening 14, once the effervescing has be gun, creates a current through the container and thus facilitates entrance of the Water through the openings 11 while the effervescing action, as will be readily appreciated, serves to distribute the radium emanation through the bath.

Having thus described my invention I claim: f

l. An effervescent salt unit comprisinga perforated container carrying bicarbonate of soda, acid sodium sulphate, radium-barium chloride, and a removable moisture-excluding wrapper carried by said container, and sealing the perforations thereof against the ingress of moisture.

2. An elfervescent salt unit comprising acontainer having perforations and carrying crystalline bicarbonate of soda, crystalline acid sodium sulphate, and radium-barium chloride, and a moisture-excluding Wrapper carried by said container and sealing the perforations thereof against the ingress of moisture.

3. A salt unit adapted to be placed-in a bath to effect effervescence and distribution of an activating material comprising a container provided with perforations and hav ing a portion adapted to be removed to provide an exit opening, crystalline bicarbonate of soda carried Within said container, crystalline acid sodium sulphate mixed with said bicarbonate of soda, and radium-barium chloride mixed with said acid sodium sulphate.

Inktestimony whereof, I have atlixed my signature to this specification.
